To all whom tummy concern: 7 lBjeit known that l, Unnsnnn 1E. Mrcnaun, a citizen of the "United States, and a resi dent of the city of St. Louis and dtate of Missouri, have invented a new and useful improvement in Roller-Bearings, of which the following is aspecification.

This invention relates to antifriction hearin of the t pe wherein a series of cylindrical or conical rollers are spaced circumferentially between inner and outer concentric bearin races or rings. The invention relates to t e shape and arrangement of the parts of the bearing, and particularly'to an improved spacing and retaining device for hearing rollers having necks of reduced diameter between their ends, for holding them in circular alinement at fired distances apart around the inner bearing rings.

said improvements beingmore fully pointed out hereinafter. a

Generally stated, the invention consists in the combination of a series of cylindrical or conical rollers which are circumferentially grooved or necked to form a head at one end of each, and arranged around a .roller race-way or bearing ring having a flange around it which fits in the grooves under the necks of the rollers, with a specing member or cage for maintainin the rollers in parallel alinement and equl-distantly spaced around the bearing ring, and a retaining hand surrounding the rollers and lying in the grooves over their necks for holding the rollers and the cage in assembled position. v The invention also consists in the shape'and construction of the ca e, and in the means for holding the ends of t e retaining hand together.

The invention further consists in the parts, and in the arrangements and combinations of arts, hereinafter described and claimed.

he accompanying drawings illustrate a preferred form of the invention, embodyin straight rollers, but it is to he understoo 'ca e and retaining band assemble nennnrannnimrs.

Fig. 5 is a side elevation to the same scale as Fig. t of portions of two rollers and the ends of the retaining ring, showing the looking means for holding the ends of the retaming ring together-g I Fig. 6 is alongitudinal section of the same on the line t -t in Fig. a;

Fig. l is a perspective view of the looking member for the retaining ring;

Fig. 8 is a perspective view of a roller;

Fig. 9 is a side elevation of the spacing cage; and

Fig. 10 is a perspective view of the retaining ring.

Referring to the accompanying drawings, the inner bearing ring 11 of the roller hearing has an exterior circumferential rib or flange 12, one edge of which is beveled. The bearing rollers 13 are cylindrical, and each comprises a main hearing portion and a head tlh lift

it connected by a neck 15 of reduced dilldlll lhli brace theirollers. The ends of the spacing -.member are turned out to form flanges 19 which cross the ends of the rollers. A rew n ng. band 20 encircles the necks of the rollersiand holds them in position in the slots of the spacing cage). The retaining ring'lies in the grooves tween the rollers and the outer bearing ring, and is held 1n alinement thereby.

The'ends of the rollers opposite their heads-have conical depressions 21 in them j at their .oenters, and projections 22 from the adjacent end flange 19 of the spacing member fit into these conical depressions and hold the spacing member in circumferential alinement with the ends of the. rollers. The band of the retaining member encircles, the bearing rollers and positively prevents them from moving outwardl from the inner hearing rin and the cylmdricallportions and ythe heat 14 of the bearing ro ers 13 straddle the flange 12 of the inner bearing ring 11 and prevent the rollers from slipping endwise. The band and intermediate portions of the spacing members encircle closely the necks 15 of the bearing rollers, and the retaining member is thereby held against 1 movement lengthwise of the rollers. The

' bearin outer bearing ring 17 can he slipped into place endwise over the rollers until the beveled inner face of the flange 16 brings up against the outer beveled edges 0 the heads 14.

The ends of the retaining ring are notched on one side to form tenons 23. which fit into a hole 24 in the sheet metal clip 25 which is bent around the ends of the ring to hold them together. The top, the bottom, and the side of the ring opposite the tenons. are

recessed to form a shallow groove around the ring for the clip 25 to lie in.

The sides of the retainin ring are provided with inwardly projecting lugs 26 /(see Fig. 10) for positioning the'rmg and spacing cage in circumferential alinementor' separate spacers having notches in their outer edges may he slipped between the ring and spacing cage for tnc.

olding them concen-' reaming them after the e restricted to the details of aaeaesa cumferential alinement, a retaining rin lying in said grooves and surrounding sai rollers, and a cage having separators between said rollers, said retainin ring surrounding said separators for hglding said cage concentric with said inner bearing ring.

2. A roller bearing comprising an inner bearm ring, grooved rollers arranged aroun sa1d ring with their grooves m cmcumferential' almement, a retaining rin lying in said grooves and surrounding sai bearing ring, grooved rollers arranged around said ring with their grooves in circumferential ahnement, a retaining rin lying in said grooves and surrounding sai rollers, and a cage having separators be tween said rollers, with outwardly pro'ecting portions between said grooves, sai retam ng ring embracin the outwardly projectmg ortlons of sai separators for holdmg sai cage concentric with said inner bearing ring. v

4. A retaining ring for bearings comprisindg grooved rollers said retainin ring being a apted to lie in the grooves o the rollers, and having tenons projecting transversel at its ends, anda clip for securing the endg of said ring together, said clip having a recess adapted to embrace said tenons, and a flexible end adapted to be bent around said retaining ring to hold it in securing position.

5. A retainin ring for bearings comprising grooved ro ers, said retaining ring being adapted to lie in the grooves of the rollers, and having tenons projecting transversely at its ends, and a clip for securing the ends of said ring to ether, said clip consisting of a strip of s eet, metal having a hole through it adapted to embrace said tenons, the ends of said strip being ada ted to be bent around said retaining ring to old it in securing position.

6. A roller bearing comprising a bearing ring and a series of rollers having ooves a spacing member having pockets or said rollers, and a retaining ring lying in the grooves of said rollers, said retaim rin and spacin member being concentric, an means in t e spaces between said ring and spacing member for maintaining them concentric, said means consisting of wings on one of said members bent to engage the other member.

7. A roller bearing comprising a spacing naeaeaa cage having a series of pockets, rollers mounted in said pockets, sald rollers being grooved at one end to form heads, and the opposite ends of said rollers heing recessed to receive centers, and projections from the ends of said pockets to engage said recessed rollers.

8. A roller bearing comprising a spacing cage having a series of pockets, rollers mounted in said pockets, said rollers heing grooved at one end to form heads, and the opposite ends. of said rollers heing recessed to receive centers, and projections from the ends of said pockets to engage said recessedrollers, and a ring lying in the grooves ot' tilt said rollers to retain the rollers in the rooves, said ring heing attachahle and etachahle to permitthe rollers to he inserted in said pockets with their recessed ends pivoted on said projections,

9, A retainin ring for hearings comprising grooved rol ers, and a spacing. cage, said retaining ring heing adapted to lie in the grooves oil the rollers, and having spaced marginal portions ada ted to position said rin concentrically vvit in it.
